To be successful in achieving these lofty goals will require new and innovative translational research depakote 250 mg otc, as well as greater patient recognition of their valuable contribution to disease self-management and overall well-being quality 250 mg depakote. Despite significant strides in genetic testing and medical technology 250mg depakote for sale, we continue to struggle with how to effectively translate new scientific evidence into clinical practice, especially amongst complex chronic disease patient populations including heart failure. According to the Centers for Disease Control and Prevention, chronic diseases represent the leading cause of death and disability nationwide. Some trend analysts predict this chronic disease estimate will increase dramatically by 2023, unless significant changes ensue. Thus, further evaluation of more effective treatment practices to improve the quality of health care, optimize clinical outcomes and reduce unnecessary hospital readmissions related to chronic disease patients is warranted. In addition, there is a growing body of scientific evidence that has identified health literacy as a major public health issue. Mechanisms and Interventions (2013, July) report, there is further evidence supporting the need to address the silent epidemic of health literacy. Interestingly, despite strong evidence, approximately 90 million Americans struggle with low health literacy that significantly impacts their disease self-management, medication administration and receptivity of critical health information. Thus, to truly be successful in reducing the burden of chronic disease and the associated costs of preventable hospital readmissions, it is imperative that more effective knowledge transfer, clinician-patient communication patterns and understanding of the importance of health literacy be achieved. While communication failures have been shown to adversely impact disease self-management, medication administration, potentially preventable hospital readmissions and clinical outcomes, how best to address these failures warrant further evaluation. Two hypotheses were identified for this study including: (1) Heart failure patients who receive education that is health literacy appropriate will have increased knowledge of disease self-management; and (2) Heart failure patients who receive education that is health literacy appropriate will have decreased 30-day heart failure readmission rates. A heart failure nurse specialist then provided health literacy appropriate, knowledge-tailored disease self-management education to these patients, prior to post testing their knowledge of heart failure. Pre and post Dutch Heart Failure Knowledge Scale scores were subsequently compared to identify potential differences. Following screening, they were provided with health literacy appropriate education, but did not receive the Dutch Heart Failure Knowledge Scale. Therefore, their patient education was not tailored to their specific knowledge of their disease process. Subsequently, 30-day overall readmission rates were compared between the cases and the control group. To be successful in comprehending a basic food label requires three sets of skills including: numeracy (numbers), application of the written word (prose) and understanding of forms (documents). In essence, the comprehension of a food label mirrors the same analytical and conceptual skills necessary for following health care providers clinical instructions. The second instrument, The Dutch Heart Failure Knowledge Scale encompasses a wide knowledge base necessary for effective disease self-management of heart failure. Of significance, this instrument measures individual participants knowledge of heart failure, diet and fluid intake and recognition of early symptoms to report to their healthcare provider to avert potential complications and unnecessary hospital readmissions. Prior to widespread adoption of this instrument, van der Wal and colleagues assessed the face, content and construct validity of this scale amongst heart failure patients admitted to 19 different hospitals across the Netherlands. They found that this scale was able to differentiate between high and low levels of heart failure knowledge in this patient population (N=902) with a Cronbachs alpha of 0. In regard to ethnicity, 98% of the study participants reported being Caucasian, with only 2% being African American. Among the total of 136 heart failure patients who were screened for health literacy using the Newest Vital Sign: Health Literacy tool, 76% of the cases and 90% of the control group had a high probability of limited health literacy, as depicted in Table 1. The possibility of limited health literacy was noted in 13% of cases and 6% of the control group, with adequate health literacy noted in 11% of cases and 4% of the control group. Among the same patients screened post education, aggregate responses were correct 74. This reflects an overall 8% improvement between pre and post education on the Dutch Heart Failure Knowledge Scale. However, the statistical significance of the difference in these two proportions could not be tested at this time, due to the relatively small sample size of the cases. Yet these results do support the need for further evaluation with a larger sample size, to identify whether the application of the Dutch Heart Failure Knowledge Scale and subsequent tailoring of disease specific self-management patient education exerted a statistically significant reduction in overall 30-day hospital readmission rates. Through further research, we hope to enhance our understanding of the unique contribution of knowledge transfer and health literacy to more effective disease self-management, especially amongst heart failure patients and hospital readmission rates. More importantly, patients knowledge of their disease process can be strengthened through an inter- disciplinary approach to more effective knowledge transfer, more accurate assessment of patients level of health literacy and their ability to comprehend key aspects of their disease self-management, prior to hospital discharge. The heart failure nurse specialist is in a key position to evaluate heart failure patients knowledge prior to discharge and develop a transitional care plan that is patient, knowledge and level of health literacy specific. With considerable policy attention directed at reducing unnecessary hospital readmissions and associated costs, this intervention may play a significant role in improving clinical outcomes, quality of life and disease self- management for the heart failure population. Finally, a larger sample size to further evaluate the relationship between knowledge transfer and health literacy upon heart failure patients disease self-management and unnecessary hospital readmissions is currently under development. We believe this model may help strengthen our ability to achieve this future goal.

From 29 patients enrolled, male patients were dominant (25 patients) with age range from 39 to 74 years old with mean of age 58. Methodes The study was performed at the National Heart Center Harapan Kita, Jakarta, and was approved by the hospital ethics committee. A femoral venous puncture and insertion of electrode into the apex of the right ventricle was performed. The onset and slope were calculated 6 7 according to the methods explained by Schmidt et al. Statistical analysis Continuous variables were reported as mean and standard deviation while categorical variables were given as the number or the percentage of subjects with the characteristic of interest. Between-group comparisons of continuous variables were performed using independent t-test. Univariate relationships were tested using Chi- Square or Fischer, whichever appropriate. Result From March to June 2007, 34 patients were recruited; two subjects experienced episodes of atrial fibrillation prior to stimulation and three people had difficult vascular access, leaving 29 patients in the study. All medicine given routinely in the outpatient clinic were still taken during this study, including nitrates (72. Hemodynamic status were monitored prior to cardiac catheterization include measures of systolic blood pressure (142 +/- 26. Based on the results of coronary angiography, majority of patients showed stenosis in two coronary arteries (44. The condition causes high sympathetic activity in response to increased levels of epinephrine and 11 norepinephrine that weakens vagal activity at cardiac level. This difference is possibly attributed to the differences in stimulation methods or race. In obesity, excessive fat mobilization occurs due to increased sympathetic activity. High sympathetic activity is counterbalanced by vagal tone by directly inhibiting excitatory sympathetic innervation and adrenergic receptor inhibition. In sympathetic and parasympathetic coordination system, there is a mechanism known as accentuated antagonism in which the increased vagal activity will weaken sympathetic activity to target organs. This activity is especially effective at prejunctional and postjunctional level of the neuroeffector junction. This is in contrast with studies reporting that declined cardiac function and heart failure condition were known to increase sympathetic activity exceeding vagal activity. This difference may be due to different stimulation methods or racial differences between each study.

A reserve of cryopreserved cells opens up the possibility for studies in toxicology or phylogeny, among others, with the obtained results being useful to take decisions concerning animal management from which samples were taken, from either in situ or ex situ populations. Besides cells and somatic tissue, we have also considered necessary to contemplate the specifc preservation of other biomaterials such as whole blood, urine, pulled hair and feces from which to obtain derivatives such as serum and plasma. Samples of feces or hair are frequently used as noninvasive methods of genetic identifcation (Palomares et al. Fecal samples are also used to identify gastrointestinal parasites (Rodrguez and carbonell, 1998) or monitoring reproductive activities through the measurement of different metabolites (comizzoli et al. In this sense, we have recently started a new study concerning the intestinal parasites present in the Iberian lynx population from the fecal samples preserved in the bank. The somatic cell reserve refects a very important fraction of the populations diversity which, in the future, will allow to extrapolate the results from specifc studies to most of the population.

A lo largo de dcadas de estudio, se ha aprendido mucho sobre la biologa de las gatas domsticas, incluyendo la funcin endocrina. Adems, investigaciones comparativas recientes sobre endocrinologa han ampliado considerablemente 327 nuestros conocimientos sobre felinos silvestres. Esto ha sido posible en gran medida gracias al desarrollo de tcnicas no invasivas de anlisis de metabolitos de esteroides en heces, que constituye el mtodo de eleccin para el seguimiento de la funcin endocrina en especies silvestres, incluyendo a los felinos. Se reconoce ampliamente que entre los felinos existen distintos patrones endocrinos, de los cuales muchos rasgos y mecanismos son poco comunes o incluso nicos. Existe una gran variabilidad en el tipo de ovulacin (espontnea frente a inducida) en este taxn. Incluso en una misma especie, algunas hembras slo presentan ovulacin inducida, mientras que en otras tambin se da la ovulacin espontnea. El metabolismo de esteroides tambin presenta diferencias: los metabolitos se excretan casi exclusivamente en las heces, con muy poca presencia de esteroides en la orina. Las distintas especies presentan grandes diferencias en cuanto a las infuencias estacionales y sociales sobre la reproduccin, las respuestas suprarrenales al manejo de la especie en cautividad y la respuesta ovrica a los procedimientos de reproduccin asistida. Por consiguiente, el desarrollo de estrategias para la mejora de la salud y la reproduccin de los felinos se debe realizar caso por caso.

Pa l a b R a s c l a v e Reproduccin, esteroides gonadales, seguimiento no-invasivo, hormonas fecales ab s t R a c t The ability to track gonadal and adrenal activity via hormones is key to optimizing health and reproduction. Through decades of study, a great deal has been learned about the biology of female domestic cats, including endocrine function. More recently, comparative endocrine studies have greatly expanded our knowledge base of non- domestic felids as well. The latter has been possible largely through the development of non-invasive fecal steroid metabolite analysis techniques, which currently is the method of choice for monitoring endocrine function in wildlife species, including felids. It now is well-recognized that a range in endocrine patterns exists among Felidae, with many traits and mechanisms being uncommon, if not unique. Even within species, some individuals exhibit ovulation that is only induced, whereas others ovulate spontaneously as well. Steroid metabolism also differs in that metabolites are excreted almost exclusively in feces, with very little steroid found in urine. Across species there are marked differences in seasonal and social infuences on reproduction, adrenal responses to husbandry practices, and ovarian responses to assisted reproductive procedures. This means that developing strategies to improve health and reproduction of felids must be done on a species by species basis. This presentation summarizes current knowledge on the reproductive endocrinology of female domestic and non-domestic cats, and describes how the rapidly growing endocrine database is aiding ex situ management efforts. Hormones are the essence of reproduction; thus, understanding the factors that infuence endocrine function is key to maximizing reproductive success. Systematic studies of felids began in the mid-1970s, focusing primarily on fundamental patterns of hormonal activity in the female domestic laboratory cat (Felis catus) (Goodrowe et al. Blood samples collected over time and analyzed for pituitary gonadotropins and ovarian 329 steroids provided a foundation for understanding the duration of the reproductive cycle, time of ovulation in relation to mating, and dynamics of hormone secretion during P pregnancy. Early reports based on repeated anesthesia and blood sampling also described estrous cycle hormone patterns in a few wild felid species (Schmidt et al. Scientifc papers began emerging in the 1980s demonstrating that steroid metabolites could be measured in urine and/or feces in an array of species (Lasley and Kirkpatrick, 1984). For most species, the decision to measure fecal or urinary hormones is determined by which material is easiest to collect, process and analyze. In the case of felids, urinary analysis of reproductive steroids is not a viable option because steroids are excreted almost exclusively in feces (Shille et al. High performance liquid chromatography and gas chromatography/mass spectrometry determined that: 1) estradiol- 17 is voided in nearly equal amounts as unconjugated estradiol and non-enzyme-hydrolyzable estrogen conjugates (3-sulfate, 17-sulfate and 17-sulfate) (Shille et al. Extracting steroid metabolites from feces generally involves boiling, vortexing or shaking samples in combinations of organic (e. Because some metabolites are conjugated, the inclusion of 10% water can increase extraction effciency signifcantly over organic solvents alone. Within sample variability can be reduced by drying feces and mixing the powder before extraction (Brown et al. Because estradiol-17 is excreted in its native form and as conjugates, both estradiol-specifc and broad spectrum (e. By contrast, luteal activity is best defned using group-specifc antisera that crossreact with excreted free and presumed conjugate pregnane metabolites. Based on regular fuctuations in estrogens, unbred domestic cats have an estrous cycle length of ~2 weeks, with estrus lasting 3-7 days. On Day 3 of estrus, behavioral signs are strongest in association with peak estrogen secretion (Tsutsui and Stabenfeldt, 1993). One thing noted in our laboratory is that in some species (ocelot; lynx; jaguar, Panthera onca) fecal progestagens are increased during estrogen surges, correlating as high as r=0. The progestagens are probably of follicular origin, because concentrations are only a fraction of those observed after ovulation. Another fnding is the occurrence of variable periods of follicular inactivity not associated with season (e. In each of these species, cycles have been observed in every month of the year, but for many individuals not continuously. In cheetahs, periods of alternating estrous cyclicity in some group-housed females suggested that enforced social living might be suppressing reproductive activity (Brown et al. Average fecal estrogen concentrations were lower in paired cheetahs, with subordinant females being more suppressed than dominants. Separation of the pairs resulted in a reinitiation of normal cyclic ovarian activity (Wielebnowski et al. The one exception was a bonded pair where only affliative behaviors were observed, and there was no suppression of follicular estrogenic activity in either female. These results suggest that estrous cyclicity may be inhibited in paired cheetahs even when aggressive interactions are relatively minor, and that social compatibility is important for maximizing reproductive success.
